I hate my "reaction" time - I'm very aware of what goes on during the considerable time it takes between me seeing the thing turn green, and my mind instructing my hand to respond.
It's like when Homer found a $20 bill under the sofa.
Homer - "Aww, twenty dollars, I wanted a peanut."
Brain - "Twenty dollars can buy many peanuts!"
Homer - "Explain how."
Brain, slowly - "Money can be exchanged for goods and services."
Homer - "Woohoo!"
Really slow, drawn out process, unfortunately.
This is why I eventually stopped playing Counterstrike online. Pathetic reaction time earns you very few kills and lots of time spent simply observing the game.
